For K=1 TO 20

For K=1 TO 20 For K=1 TO 20 VB题 a=5 For k=1 To 0 a=a+k Next k Print k；a VBA,定义一个二维数组arr(1 to 20,1 to y),求arr(k,1 to y)的平均数和标准差?For k = 1 To 20avg(k) = Application.WorksheetFunction.Average(arr(k,1 to y))std(k) = Application.WorksheetFunction.StDev(arr(k,1 to y))'红色报错,请问averag p=1 For k From 1 To 10 Step p=p+2*k-6 End For Print p SET TALK OFF CLEAR FOR I=1 TO 20 FOR J=1 TO 33 FOR K=(100-I*5-J*3)*3 IF I=J=K=100 I,J,K ENDIF ENDFOK=(100-I*5-J*3)*3 提示语法错误SET TALK OFFCLEARFOR I=1 TO 20FOR J=1 TO 33FOR K=(100-I*5-J*3)*3IF I=J=K=100I,J,KENDIFENDFORENDFORENDFORSET TALK ON MATLAB运行时：Attempted to access (1,0); index must be a positive integer or logical.for N=1:1:8 for k=0:1:20 A(N,k)=0 endend?

A:=10;B:=50; FOR K:=A TO B DO BEGIN K:=K+1;{这一句是错误的!} WRITELN (K); END;A:=10;B:=50; FOR K:=A TO B DO BEGIN K:=K+1;{这一句是错误的!} WRITELN (K); END; 在pascal语言中怎么改正过来, 有如下程序dim arr(3,3) for j=1 to 3 for j=1 to 3 arr(j,k)=(j-1)*3+k next k next j有如下程序dim arr(3,3) for j=1 to 3 for j=1 to 3 arr(j,k)=(j-1)*3+k next k next j for j=2 to 3 for k=2 to 3 print arr(k,j); next k print next j 运行程序后 For i = k - 1 To 1 Step -1 特别是为什么用step?） vb题,For i=1 to 2 for j=1 to 2 for k=1 to jvb题,For i=1 to 2for j=1 to 2for k=1 to ja=a+2next knext jnext i最后变量a的值为10,怎么算, VB程序里 For k=1 to 10 step 它会有什么结果?
